Activation energy for the acid catalyzed hydrolysis of sucrose is 6.22 kJ mol –1 , while the activation energy is only 2.15 kJ mol –1 when hydrolysis is catalyzed by the enzyme sucrase. Explain.

Question

Activation energy for the acid catalyzed hydrolysis of sucrose is 6.22 kJ mol –1 , while the activation energy is only 2.15 kJ mol –1 when hydrolysis is catalyzed by the enzyme sucrase. Explain., Enzymes increase the temperature, reducing the activation energy required for reactions., Enzymes increase the concentration of reactants, lowering the activation energy barrier., Enzymes, the biocatalysts, reduce the magnitude of activation energy by providing an alternative path. In the hydrolysis of sucrose the enzyme sucrase reduces the activation energy from 6.22 kJ mol –1 to 2.15 kJ mol –1 ., Enzymes reduce the pressure in the reaction, affecting the activation energy.

MARKS App · Accepted Answer

Correct Option is : (C) Enzymes, the biocatalysts, reduce the magnitude of activation energy by providing an alternative path. In the hydrolysis of sucrose the enzyme sucrase reduces the activation energy from 6.22 kJ mol –1 to 2.15 kJ mol –1 .
